  • smarty练习：数据的增删改

    根据数据库中的三张表格：timu，xuanxiang，kemu来进行数据的增删改查，并且使用smarty模版将前端与后台分离开来 

    三张表格：

    主页面后台 main.php:

     1 <?php
 2 //引入配置文件
 3 include("../init.inc.php");
 4 //引入数据库
 5 include ("../../DBDA.class.php");
 6 $db=new DBDA();
 7 $sql="select * from timu";
 8 $attr=$db->Query($sql);
 9 //注册变量
10 $smarty->assign("shuju",$attr);
11 $smarty->display("main.html");
    View Code

    主页面前端 main.html:

     1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

17     <td>操作</td>
18 </tr>

20 <{foreach $shuju as $v}>
